High (7.4) in cisco telepresence video communication server. EPSS 0.7% chance of exploitation in the next 30 days.
A vulnerability in the REST API of Cisco Expressway Series and Cisco TelePresence VCS could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack on an affected system.
This vulnerability is due to insufficient CSRF protections for the web-based management interface of an affected system. An attacker could exploit this vulnerability by persuading a user of the REST API to follow a crafted link. A successful exploit could allow the attacker to cause the affected system to reload.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
